Research shows that attachment patterns—our patterns of relating to others, which develop in early childhood—affect far more aspects of our lives than was previously thought.Given how crucial these patterns are to how every patient relates to the world and to their own selves, how can therapists harness attachment to provide more effective therapy?Using AEDP® psychotherapy theory and methodology as a foundation, the authors present an innovative approach that tailors treatment to attachment patterns, allowing psychotherapists to help patients heal relational trauma.Here, readers will find attachment pattern-specific clinical interventions to help them translate attachment theory into transformative clinical practice. Case examples are used throughout to illustrate how to handle the unique challenges that psychotherapists encounter with each attachment pattern, while engaging commentary discusses how the attachment-informed experiential/relational process leads to healing attachment trauma and facilitating security, resilience and well-being.
